He began working in the pollution control industry in the early 1990's. He received his bachelor's degree in Mechanical Engineering from the University of Texas at Austin in 1989. During the past decade his work has focused upon developing cost-effective methods for reducing regional mobile source pollution. In that capacity, his primary clients have been state and national governments, mainly in North America. His work over the past 5 years can be summarized as covering the following subjects: • the design and evaluation of inspection and maintenance programs; • the development and application of mobile source emission factor models; • investigations into the effectiveness of techniques and technologies for measuring and reducing mobile source emissions; and, • the development of regional strategies for reducing mobile source emissions. Mr. Walters has authored several peer-reviewed articles on mobile source pollution control and has spoken at numerous symposia and conferences during the past decade. He holds two patents for pollution control equipment. <img class="alignnone size-medium wp-image-14597" src="../../wp-content/uploads/2022/04/E6AE9B56-04DE-478A-9214-E9E09CEE9D12-260x300.jpeg" alt="" width="260" height="300" /> <hr /> <table border="0" width="490"> <tbody> <tr> <td colspan="2" valign="top"> <h3>EDUCATION</h3> </td> </tr> <tr> <td colspan="2" valign="top"> <table border="0" width="490" cellpadding="3" align="left"> <tbody> <tr> <td align="left" valign="top" width="185">B.S.

Andrew Bennett

Senior Site Engineer
📍London Andrew Bennett came to Canada in 2001. Once here, he found it could have been beneficial to obtain some additional certifications in England. This would have made becoming a civil engineer in Canada much easier. <p class="p1"><span class="s1">Wanting to start a family in Canada, Bennett, a civil engineer from England, arrived in Toronto in 2001.</span></p> <p class="p1"><span class="s1">Before coming to North America, Bennett earned a Bachelor of Technology in Civil Engineering (B.Tech) and a Master’s Degree in Civil Engineering (M.Sc). Both degrees were instrumental in starting a successful, nine-year career as a structural engineer and later as a lecturer in an English university.</span></p> <img class="alignnone size-medium wp-image-14742" src="../../wp-content/uploads/2023/03/0130EA73-0221-474B-A7AA-69E0D2DDDCC7-300x300.jpeg" alt="" width="300" height="300" /> <p class="p1"><span class="s1">“As soon as I arrived in Canada, I tried to look for a job as a civil engineer. I sent some applications and got a phone call, but I never had an in-person interview. They told me I needed to get Canadian experience,” Bennett recalls.</span></p> <p class="p1"><span class="s1">To be a professional engineer (P.Eng.) in Canada, an internationally-trained foreigners needs to become licensed by a Canadian engineering association. However, individuals can still work in engineering —even without a license— as long as they are supervised by a P.Eng. Even with this knowledge, Bennett’s lack of Canadian experience became an obstacle.</span></p> <p class="p1"><span class="s1">Realizing it was going to be challenging to find a job at the same professional level as the one he previously held internationally, Bennett went back to England a couple of months after arriving in Canada. In England, he had maintained a job as a lecturer in a university and was required to complete his contract.</span></p> <p class="p1"><span class="s1">After six months, he returned to Canada and applied to the Engineering Skills Enhancement Bridging Program at Humber College. He wanted to be trained in the latest technical and software skills that were in demand by Ontario employers, as well as to sharpen his communications skills.</span></p> <p class="p1"><span class="s1">“I found out about Windmill Micro Lending through Humber College. At that time, I was unemployed. I applied for the loan and received the help that I needed. With the loan, I paid for the program,” Bennett says.</span></p> <p class="p1"><span class="s1">After only one month in the program, Bennett got his first job as a Quality Control Inspector at a well-known construction company in Canada. He was able to work full-time because his classes took place evenings and weekends. For eight months, Bennett did asphalt mix design and quality assurance, as well as control of asphalt materials.</span></p> <p class="p1"><span class="s1">“It wasn’t easy to get my first job. I lacked the knowledge on how to go about getting a job. I thought a lot about going back to England for good,” Bennett comments.</span></p> <p class="p1"><span class="s1">After completing the program, Bennett received a Certificate of Achievement from Humber College and a one-year membership with the <span class="s2">Ontario Society of Professional Engineers (OSPE)</span>. </span></p> <img class="alignnone size-medium wp-image-14743" src="../../wp-content/uploads/2023/03/D89A8C5E-FC2E-495E-8FCF-8AC874EDDDB7-300x197.jpeg" alt="" width="300" height="197" /> <p class="p1"><span class="s1">A few months later, he left his job for a new role as a Senior Field Inspector in a company that provides engineering and construction services in various industries.</span></p> <p class="p1"><span class="s1">In the meantime, and through <span class="s2">Construction Specifications Canada (CSC)</span>, Bennett completed an additional program and became a Certified Construction Contract Administrator (CCCA).</span></p> <p class="p1"><span class="s1">Now, Bennett works as Construction Inspector on a water main project at a firm that provides management and consultancy services. Although this position is at the same professional level as the one he had in England, Bennett’s plan is to return to academia.</span></p> <p class="p1"><span class="s1">“All my academic research in England was based on construction materials and how they could be improved. I wish I could still go on that path, hopefully in the future,” Bennett explains.</span></p> <p class="p1"><span class="s1">Although Bennett isn’t a P.Eng. in Canada just yet, he has been an engineer-in-training since 2017 and hopes to soon become a fully qualified engineer. Since he is gainfully employed now, he wants to take his time accumulating experience and studying for the mandatory <span class="s2">Professional Practice Examination (PPE)</span>, which tests a professional’s knowledge of ethics and Canadian law as it relates to engineering.</span></p> <img class="alignnone size-medium wp-image-14744" src="../../wp-content/uploads/2023/03/C180E877-E5CF-4069-8AB6-CD7B6A631A93-212x300.jpeg" alt="" width="212" height="300" /> <p class="p1"><span class="s1">“As a civil engineer from another country, you must upgrade your knowledge and obtain a Canadian certification. It’ll help improve your odds of getting a job interview and probably the job. If you have to take a loan for that, do it. It’ll pay off in the end.”</span></p> <p class="p1"><span class="s1">If there is one thing Bennett misses the most about England, it’s his network. “You never know that you have a network until you move to another country and see how important it is to have networks in your professional field. I moved to Canada, and I saw the effect of the networks. It’s not just about getting the job; it’s about having the right information.”</span></p> <p class="p1"><span class="s1">Three years have passed since Bennett arrived in Canada, and he’s still amazed at how diverse the Greater Toronto Area is. “There’s probably a person from every country in the world [here]. It amazes me how easily you come across a lot of people from so many countries. Many of whom I never thought I was going to see in my life.” Bennett is now Back in London.</span></p>
